Now that Iran is sort of used to how Israel does stuff, the fear and shock from it is no longer there.
The real worrying concern is if the US gets involved directly now. I think it's pretty hard for Iran to find a way out of that one.
Iran's biggest move would be waiting for the best time (when as many forces are concentrated in the Gulf as possible) to close the Straits of Hormuz through mining and striking all hostile naval ships and bases inside the constrained Gulf from short range with ASMs, attack boats, mini-subs and USVs.
This would inflict immediate damage and provoke a ground war. They need to have the will to fight to the end though and accept that they will become a war torn nation for 10+ years no matter what at this point. No more Instagram, parties, etc, only fighting for survival. The outcome is remaining independent and reestablishing deterrence. The alternative would be becoming an even worse shithole being run by ISIS or the kings again, while inflicting 0 damage and becoming a global laughing stock.
Iraq only recovered the nominal GDP per capita of Saddam era Iraq in the 1980's, in 2017, so Iranians have that to look forward to if they surrender. Saddam thought he could negotiate too.
